What are the standards for appointing moderators on Fluther?

It seems we’ve been talking more about the role of moderators on the site lately, and things like political and religious inclinations and how that might influence things. It got me to wondering about how they’re chosen. I’ve moderated on other sites, and usually it’s mostly to do with demonstrating an ability to maintain the guidelines. On a site with a sort of intellectual focus like Fluther, are there intellect-related standards? Other qualities? What say our friendly mod squad?
